MOTOR FUEL AND COOLING- SYSTEM.

Application filed March 8, 1922. Seriallbie 540,909.

To all whom it may concern.

Be it known that I, RUDOLPH KnoLmen, a citizen of the United States, residing at McGregor, in the county of McLennan and State of Texas, have invented certain new and useful Improvements in Motor Fuel and Coolin Systems, of which the following is a speci cation. I I

This invention relates tonew and useful improvements in motor fuel and cooling systems.

The object of the invention is to provide a system for utilizing a heavy hydrocarbon oil as fuel for 'an internal combus tion engine and at the same time employing said oil in the cooling system in the place of water or air.

A particular object of the invention is to use a heavyhydro-carbon oil such as crude oil in the'circulatory coolin system which includes the radiator and jac et of a motor; together with means for heating, like fuel oil and introducing it in the circulate system so as to replenish the same wlthout materially reducing the temperature and at the same time introducing air, whereb the oil in the circulatory system in aerate and a gaseous vapor produced in a chamber provided for this purpose.

A still further object is to convey this gaseous vapor from its collection chamber and introducing it into the intake manifold of the motor, whereby a highl combustible and efiicient fuel is provided. ne of the fea- I tures resides in introducing the heated fuel oil into the circulatory system at a plurality of points whereby it is broken u and more readily gasified. A further ob ect is to provide a safet outlet for the gaseous vapors which will operate under an excessive pressure and convey said vapors back into the fuel line so that the same will not be wasted. a

A construction designed to-carry out the invention will be hereinafter described -together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Fig. 8 is a view'of a modified form of construction, partly in elevation and partly-in section. i

In the drawings the numeral 10 designates the block of a motor which contains the usual cylinder surrounded by the ordinary circulatory jacket. A radiator 11 is mounted in front of the ,block and is provided with a top tank 12 having a filling cap 13. A fuel tank 14 is mounted over the block. The circulatory jacket of the block communicates with the tank 12 by a connection 15 and with the radiator b aconnection 16 at the lower end thereof. The usual exhaust manifold 17 and exhaust pipe 18 are rovided. -A- gasoline tank 19 is mounte on the. side of the block and is connected with a carburetor 20 which in turn is suitabl connected with an intake manifold 21.

fan 22 is mounted on the rear of the radiator and is provided with "a shaft 23 which is driven in the usual manner. The parts which have been described form the elements of a well known make of tractor and are not a part of the invention, but are merelyaccessories thereto. It is to be understood incarrying out the invention the same may be applied to any make of tractor which employ a cooling system involving a circulating fluid and a radiator.

In applyingmy inventionto the tractor, I provide. a glass gauge 24 which I mount on the side of the radiator so that its upper end connects with the tank 12 of the center thereof. I provide the cap 13 with a suitable gasket or other means whereby a pressure tight joint may be had. A. pressure gauge 25 is mounted on'top of the-tank. I remove the kerosene burning carburetor and extend a fuel pipe 26 from the bottom of the tank 14 to the top of-a cylindrical drum 27 This, drum surrounds the exhaust pi e 18 and is-provided with drain cocks 28 in its bottom. Crude oil or other hydro-carbon pump cylinder 32 and includes a check valve 33 adjacent said pump. The pump is operated bya crank shaft 34 mounted on the side of the block 10 and driven by means of a chain 35 from the fan shaft 23. Another feedpipe 36 leads from the pump cylinder and includes a check valve 37. These valves are arranged alternately so that when one is closed the other is open J as is obvious. The pipe 36 extends upwardly and passes betweenthe block and the radiator and isconnected on the opposite side with a manifold 37 which has a plurality of spaced nipples 38 connected in the return manifold 39 of the circulatory jacket of the block.

The radiator and tank 12 are filled with crude oil, or other fuel oil, by removing the cap 13. The oil level is brought to the point shown in Fig. 1, and will be indicated in the gauge 24.. The cap 13 is replaced and sealed in a suitable manner as by a packing gasket. This leaves a space at the top of the tank above the oil level which forms a vaporizing chamber or dome.

Between the valve 30. and the check valve 33, a T-joint 40 is connected in the pipe 31 and receives the lower end of the sleeve 41. The upper end of this sleeve is open to admit air which is drawn down thru the sleeve and introduced into the oil which is flowing thru the pipe 31. The oil which is pum ed thru the pipe'36 is not only heated, ut

,is aerated and this promotes vaporization.

By passing the aerated oil from the manifold 37 thru the multiplicity of nipples 38, said oil is broken up and is more readily 'gasified. The aerated oil is caused to circulate thru the jacket and radiator and pass thru the body of oil which is previously introduced to the same, whereby the temperature of the body of oil is raised and gaseous vapors formed in the tank 12 at which point the discharge from the jacket of the motor enters. These gaseous vapors form an excellent fuel and may be introduced directly into the motor cylinders with out employing a carburetor.

The gaseous vapors which are collected in the dome of the tank 12 are conveyed thru pipes 42 to regulating valves 43 Which are mounted at each end of the intake manifold 21. In eachQpipe 42, a plurality of check valves 42' are connected for preventing back fire from the motor passing to the dome. In order that the valves 43 may be easily adjusted and in unison, I provide a worm shaft 44, having a crank 45 on its rear end and mounted on the block 10. The shaft is supported in a bracket 46 mounted on the manifold 21 and has worms 47 integral therewith. The bracket has upstanding yokes 48 in which the extended hubs of worm gears 50 are journalled. These gears mesh with the worms and are revolved thereby. The stems 49 of the valves are angular in cross section and pass snugly thru the gears so as to be rotated by the gears. The valves 43 are of the globe type in which the stems are threaded, so that by rotating said stems the valves are opened and closed. The crank 45 is within easy reach of the driver and he may readil ad- 'ust the valves 43 to control thesupp y of fuel to the motor.

It is obvious that means must be provided A for relieving excess premure from the dome 13, which pressure is indicated by the gauge 25. A pressure release valve 51 of any suitable construction is connected in the top of the tank 12 and arranged to release at a given pressure, the vvapors or gases, to a pipe 52. The pipe 52 passes down into the sleeve 41. It is obvious that the cold air which passes into the sleeve will cause a condensation of the gases and the condensate will pass down into the pipe 31.

In using the apparatus the carburetor 20 is supplied with gasoline from the tank 19 in the usualmanner. The charge from the carburetor is drawn into the manifold 21 and the motor operated in the ordinary way. The exhaust passin thru the pipe 18 will heat the drum 27. Crude oil or other fuel liquid is placedin the tank 14, and fed to the drum thru the pipe 26; the radiator and motor jacket having been filled with the same character of fuel oil. The oil in the circulatory system is circulated whereby the motor is cooled and the temperature of said oil raised. The hottest oil will be discharged from the jacket thru the connection 15 into the top tank 12 and in a shorttime after the motor has been started the oil in the tank 12 will begin to vaporize and the gauge 25 will indicate a pressure.

\Vhen this condition is reached the needle valve 30 is opened soas to cause the heated oil from the drum to flow into the pipe 31. This oil being heated will be more fluent and easily handled by the pump 32. As the oil passes thru the T-joint 40, it is admixed with air from the sleeve 41 and is' thus aerated. The aerated oil is pumped thru the pipe 36 to the manifold 37 and ejected thru the nipples 38. By discharging the oil thru the many nipples, it is broken up and more readily gasified. This aerated and heated oil being introduced directly into the jacket at the bottom thereof, and being of less specific gravity that the oil returning from the radiator, will pass u ward thru.

said circulating oil until it reac es the hotter strata at the top. The air thus admitted passes into the dome and mixes with the vapors or gases being generated therein. The vapors or ases, from the dome are conveyed thru the pipes 42 t0 the'intake manifold 21.

its flow being regulated by the valves 43.-

By this system a carburetor is eliminated and only combustible gases are admitted to the motor, which makes for a great saving in fuel consumption.

It will be seen that the oil from the tank 14 is preheated and aerated, so upon entering the circulating body of oil it will have atendency to pass up thru the same and promote vaporization, rather than retard the same. At the same time. oil in the circulatory or cooling system will be replenished. The hot oil passing from the top tank 12 down thru the radiator 11 will be cooled and in this manner excessive heat from the motor will be dissipated. I

In Fig. 8, I have shown a modified form of construction that may be used in place of an ordinary radiator as described, or in connec tion with stationary engines or the like which are not equipped with a suitable fluid containing tank in their circulatory system. The modification comprises a rectangular receptacle 60 which is reduced at its upper end to form a vaporizing chamber or dome 61 having a filling opening 62. A pipe 63 or other conductor of suitable design leads from the lower portion of the receptacle to the engine jacket. The aerated and heated oils passing thru the pump 32 are conducted to the 7 means of a pipe 64. The hottest oils circulate from the engine jacket to the up erportion of the receptacle thru a, suita le connection 65. It is obvious that gaseous vapors are thus generated in the dome 61 in a manner such as has been hereinbefore described. From the dome said gases are conducted to the' intake manifold of the. engine by means of a pipe 66 or the like, as is .also obvious.
